As the world focuses on increasing global food security, it is critical to improve small farm productivity and yield, while decreasing costs, minimizing the environmental impact with precision agriculture practices, and better manage agricultural production and associated inventory. It is important to take corrective action early in the growing season by understanding crop conditions.
Factors such as crop health and stress caused by problems due to nutrient deficiency, moisture stress, and pests can be assessed and managed quickly to avoid future issues. Furthermore, with SWIR data you can go one step further and take preventive action as opposed to corrective action to ensure future crop success by assessing the soil mineral content and ensuring its compatibility with the intended crop to be planted.
WorldView-3 data is uniquely designed to observe and map these phenomena. Crop stresses change the green chlorophyll content of the leaves and replace them with carotenoids that have yellow and red colors visible wavelengths. In addition, SWIR bands are used to assess crop moisture, as another health indicator. Observing soil types and conditions before, during and after a crop season is important for managing crop health. WorldView-3 offers a window into underlying soil conditions and how such conditions might affect vegetation.
